Some important details are missing from the documentation for setting up a SharePoint development environment on Windows.
For starters, nowhere in the installation instructions is it mentioned that running npm install with --global requires running the command from an admin command prompt. Not running in an elevated prompt will not fail, instead, it will appear to work until you actually try to run any yo commands.
Next, in the section for Trusting the self-signed developer certificate, it is mentioned that you can run the gulp command after creating the project, but in the previous paragraph it says "you can do this now", but that is not possible as gulp does not actually run without a gulp file, which you only get if you have a project (with a gulp file).
